well known for their diverse structural features and biological applications. The two tin compounds, Di(m-bromobenzyl)(dibromo)tin(IV) (1) and di(m-chlorobenzyl)(dibromo)tin(IV) (2) when treated with 1, 10-phenanthroline yielded the complexes Di(m-bromobenzyl)(dibromo)(1,10-phenanthroline)tin(IV) (3) and Di(m-chlorobenzyl) (dibromo)(1,10-phenanthroline)tin(IV) (4). The molecular structure of these complexes are confirmed by spectroscopic (1H, 13C & 119Sn NMR), XRD and DFT studies. The distorted octahedral geometries with axially disposed carbon atoms are confirmed and the new complexes show better anticancer activity when compared to that of cis-platin.
